(jsp需要引入 ：jquery-1.9.0.js、jquery.form.js ) ，jsp页面使用的是bootstrap制作的，看不懂的标签不用管，form表单大同小异。代码比较简陋，只是为了演示使用ajaxSubmit异步上传图片及保存数据，请海含！

一：web (add.jsp)

public class FileUploadController {
private Logger logger;
@RequestMapping(value = "upload.do", method = RequestMethod.POST)
public void fileUpload(HttpServletRequest request, HttpServletResponse response) {
Map<String, Object> resultMap = new HashMap<String, Object>();
String newRealFileName = null;
try {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
CommonsMultipartFile file = (CommonsMultipartFile) multipartRequest.getFile("file");
// 获得文件名：
String realFileName = file.getOriginalFilename();
if(file.getSize()/1024>=5*1024){
resultMap.put("status", 1);
resultMap.put("message", "图片不能大于5M");
}else{
System.out.println("获得文件名：" + realFileName);
newRealFileName = FileUploadController.getNowTime() + realFileName.substring(realFileName.indexOf("."));
// 获取路径
String ctxPath = request.getSession().getServletContext().getRealPath("//") + "//temp//";
// 创建文件
File dirPath = new File(ctxPath);
if (!dirPath.exists()) {
dirPath.mkdir();
}
File uploadFile = new File(ctxPath + newRealFileName);
FileCopyUtils.copy(file.getBytes(), uploadFile);
request.setAttribute("files", loadFiles(request));
resultMap.put("status", 0);
resultMap.put("fileName", newRealFileName);
}
} catch (Exception e) {
resultMap.put("status", 1);
resultMap.put("message", "图片上传出错");
logger.info("***** 图片上传出错 *****");
System.out.println(e);
} finally {
PrintWriter out = null;
try {
out = response.getWriter();
} catch (IOException e) {
e.printStackTrace();
}
//必须设置字符编码，否则返回json会乱码
response.setContentType("text/html;charset=UTF-8");
out.write(JSONSerializer.toJSON(resultMap).toString());
out.flush();
out.close();
}
}
}
